Narrator: Hello students.
Now we are moving forward and for problem 2C,
The question is, "What is the probability
that a child is hyperlipidemic
if neither parent is hyperlipidemic?"
So here we have a condition attached
to both the numerator and the denominator.
First of all, we have to focus on which column right now,
we have to focus on the third column.
And here the first thing we need to identify
is the numerator, which is the child being hyperlipidemic
but neither parent being hyperlipidemic.
So that would be the numerator here is going to be six.
And then we have to identify the denominator
and that is going to be what?
That is going to be 89.
Because here, we are looking for the situation
where neither parent is hyperlipidemic.
So the denominator is going to be 89.
So basically what we are doing here is finding out
the probability that the child is hyperlipidemic,
if neither parent is hyperlipidemic.
So that's going to be the probability six
divided by 89 and that will be 0.067 or 6.7%.
So again, what is our answer here?
Our answer here is there is a 6.7% probability
that the child is hyperlipidemic
if neither parent is hyperlipidemic.
